Meyer Sound M'elodie ELECTRICAL SAFETY ISSUES

CHAPTER 2

NOTE: For best performance, the AC cable voltage drop should not exceed 10 volts, or 10 percent at 115 volts and 5 percent at 230 volts.

Make sure that even with the AC voltage drop, the AC voltage always stays in the operating windows.

The minimum electrical service amperage required by a M’elodie system is the sum of each loudspeaker’s maximum long-term continuous current. An additional 30 percent above the minimum amperage is recommended to prevent peak voltage drops at the service entry.

ELECTRICAL SAFETY ISSUES

Pay close attention to these important electrical and safety issues.

CAUTION: In the unlikely event that the circuit breakers on the loudspeaker’s user panel

trip (the white center buttons pop out), disconnect the AC power cable. Do not reset the breakers with the AC connected. Contact Meyer Sound for repair information.

CAUTION: The M’elodie loudspeaker requires a ground connection. Always use a

grounded outlet and plug.

CAUTION: Do not use a ground-lifting adapter or cut the AC cable ground pin.

CAUTION: Do not exceed the current capability of the 20-amp M’elodie loudspeaker AC

connector. When looping always take into account the current draw of all speakers in the circuit, including the ﬁrst unit.

CAUTION: Ensure that the power plug is appropriate for the AC power at the site where

you will operate the M’elodie loudspeaker. In addi- tion, the connector must be rated for the total load of all M’elodie loudspeakers looped to the same power plug.
